Abstract

In a method for the production of steel in an environmentally benign fashion, energy sources other than conventional fossil fuels (1) are used to produce reductant fuels. These reductant fuels are used for the reduction of iron ore (10) and its conversion to steel (11). Furthermore, these reductant fuels may be stored in order to smooth fluctuations in the primary energy supply. Electrical energy may be stored (8) to smooth out short term fluctuations in the primary energy source. Energy for the reduction and conversion process may be supplied in part directly from the primary energy source, avoiding inefficiencies in the production and storage of the reductant fuel. Possible primary energy sources include solar power, wind power, off-peak power supplied as part of load leveling plants, as well as conventional constant power output from an ordinary power plant (1).
